The compound is Octane since it has 8 carbons on the parent chain and has only single carbon to carbon bonds.
The small part of the nucleus where ribosomal subunit formation takes place is called the nucleolus. This structure is found in eukaryotic cells and takes up about 25 percent of the volume of the nucleus. This structure is said to be the brain of the nucleus. It is made up of ribobucleic acids or the RNA and proteins. Its primary function is to transcript the ribosomal RNA (rRNA) and to combine these with the proteins resulting to the formation of an incomplete ribosome. Since it is closely related to a chromosomal matter of a cell and important in the production of ribosome, this structure is correlated to be one of the cause of a number of diseases.

Excluding those, the most active are the lower left and upper right.So the least
active (EXCLUDING GROUP 18) are the non- metals furthest form the upper right
11. a. Amphoteric
12. a. NH₄⁺, H₂O
Explanation:
11. A substance that can act as either an acid or a base is said to be <u>amphoteric</u>.
Water is an amphoteric substance because it can reaction with either and acid or a base.
HCl + H₂O → Cl⁻ + H₃O⁺
NH₃ + H₂O → NH₄⁺ + OH⁻
12. What are the acids in the following equilibrium reaction?
NH₃ (aq) + H₂O (l) → NH₄⁺ (aq) +OH⁻ (aq)
H₂O water is acid 1
NH₄⁺ ammonium ion is acid 2

The chemical formula depends on the type of acids it is. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.
